Features: 

  1. Using high-white aluminum hydroxide as raw material, it has high whiteness and pure boehmite phase.
  2. The chemical composition is purer and the content of magnetic foreign matter is low
  3. The powder has low hardness and is suitable for coating the edges of the positive electrode sheets of lithium batteries. It can avoid burrs from piercing the separator during the slitting process of the positive electrode sheets. It can also reduce the wear of the slitting equipment and the introduction of foreign matter, and improve the yield rate of lithium batteries. and safety performance.
  4. It is also suitable for the copper-clad laminate industry. It has incomparable advantages in improving the flame retardant performance of the copper-clad laminate, improving the leakage resistance and heat resistance of the substrate.

Packaging and storage:：

Packed in moisture-proof bags, lined with plastic film bags, ton bags or 25KG/bag.

Store sealed in a cool, dry, well-ventilated place, away from direct sunlight.
